I don't have a lot of information about it but I watched White Noise with Michael Keaton last night reminded me of this movie I saw probably on Netflix.
I'm pretty sure the movie was black and white.
It was probably filmed in the 80's.
Probably an indie film.
Maybe filmed in the outback of Australia. When I think of the movie that's kind of what I picture.
Premise of the movie I think is husband loses a wife and then invents machine to communicate with her or something.
Slow developing film with a oh-that's-cool ending.
